What this grade measures
The quality of the schedule data in the feed scored here for trip-planning apps: whether riders using Google Maps, Apple Maps, or Transit see current, correct, and complete information. It measures the data feed, not service quality or operations.
Progress this period
No newly cleared items this period. The score and trend above reflect where the feed stands today.
What needs attention next
Three improvements, in priority order, each sized so the board can see what it is approving:
Remove past service periods the next time you export the feed.
Some service calendars in the feed have already ended. Expired calendars are dead weight and can hide real schedule problems from your staff and vendors.
Estimated effort: One setting in most export tools.
Ask your AVL vendor to check vehicle-to-trip assignments for the flagged trips.
36 of 99 sampled vehicle positions were far from their assigned route (worst: 32170 m). A transit vehicle shown off its route usually means a wrong trip assignment; riders watch their transit vehicle drive the wrong path.
Estimated effort: A vendor support ticket with the trip ids attached.
Check the flagged stops' coordinates and the route shape in your scheduling software; re-snap whichever is misplaced.
Some stops sit far from the route line they belong to. Trip planners may draw the transit vehicle route through the wrong path or point riders to the wrong boarding location.
Estimated effort: A few minutes per flagged stop.
